I bought an Abit KR7A-RAID and a 1800+ Athlon. The CPU soft set seems to detect it as a 2000+, any attempt to set it otherwise results in a failed boot and the only way round is to clear the CMOS and start again. The board works well with a 1GHz Duron so it's basically OK. The problem is the Athlon chip is not stable (at this speed). It's unlike my supplier to give me something for nothing so is there a way to identify the speed of the chip? I've done a BIOS upgrade and the same happened befor and after. By the way, I say that I'm a reluctant overclocker 'cos I'd trade any gains in speed for stability. Thanks for any ideas

WCPUID and Sisoft Sandra will both identify your CPU chip properly. It almost sounds like the FSB has been bumped up or the L1 traces have been connected (take a look).

Thanks, but that assumes I can get into Windows. I've tried the CPU in another motherboard and a similar thing happens. I think it's a DOA.

The replacement worked OK first time.

Hi, My system is about the same but have the non raid board. My xp1800 works just fine........have you selected cpu 1800 in bios..with 133mhz fsb and 11.5 multiplier..?? For fun, I tried other settings and puter told me to get knotted...lol
